Sažetak

A twenty-three step alkaline permanganate degradation of
kerogen from Aleksinac (Yugoslavia) shale was carried out. A very
high total yield of oxidation products was obtained (92.840/0 based
on original kerogen). Detailed GC-MS analyses of ether-soluble
acids, soluble products of further controlled permanganate degradation of precipitated acids and acids from aqueous solutions,
served as basis for quantitative estimation of the participation of
various types of products and for comparison with other kerogens
based on similar criteria. The prevailing saturated long-chain aliphatic
structure of oxidation products suggested a predominantly open-chain cross-linked aliphatic structure of Aleksinac shale kerogen, classified as type Ikerogen. Nevertheless, noticeable proportion of alkane-polycarboxylic and aromatic acids in the oxidation products indicated a larger share of alicyclic, heterocyclic, and aromatic structures in this kerogen. Oxidative degradation products were shown to enable more precise structural interpretation than the classification based on elemental analysis.
